Description

Technical Field

[0001] This utility model belongs to the technical field of continuous casting machine equipment and relates to a continuous casting secondary cooling chamber pipe that can discharge sewage during online production. Background Technology

[0002] The secondary cooling chamber pipe is a crucial piece of equipment in the billet continuous casting machine. The secondary cooling water sprayed from the nozzles on the pipe provides uniform cooling of the billet, ensuring billet quality and improving casting machine efficiency. However, sludge and debris in the secondary cooling water tend to settle and accumulate at the lower end of the pipe. Due to the difficulty of cleaning the inside of the pipe, effective cleaning is often impossible over time. Each time the water supply is interrupted and restarted, the settled sludge and debris at the lower end of the pipe are easily washed up and carried into the nozzles with the secondary cooling water, causing blockages and hindering water spray, thus affecting the uniformity of billet cooling. Furthermore, as more and more sludge and debris accumulate at the lower end of the pipe, the water spray channel from bottom to top is gradually blocked, rendering the pipe unusable and necessitating replacement, thus reducing its service life.

[0003] Although secondary cooling water pipeline filters are currently used in the continuous casting industry, these filters can remove sludge and debris from the secondary cooling water sent to the continuous casting plant by the pump station. However, due to long-term use, sludge deposited in the pipeline between the filter and the discharge pipe, as well as oxide slag that has detached from the pipeline due to corrosion, will enter the discharge pipe along with the secondary cooling water. This causes sludge and debris to easily settle and accumulate at the lower end of the discharge pipe, and existing technology cannot solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the problem of difficult cleaning of debris from the secondary cooling chamber pipes of continuous casting machines in the background art, and to provide a secondary cooling chamber pipe for continuous casting that can discharge debris during online production.

[0005] Therefore, the present invention adopts the following technical solution:

[0006] A continuous casting secondary cooling chamber drain pipe capable of draining wastewater during online production includes a secondary cooling chamber body. The secondary cooling chamber body is provided with an arc-shaped drain pipe. Multiple nozzles are provided along the length of the drain pipe. A water supply pipe is connected to the bottom end of the drain pipe. The water supply pipe is connected to a wastewater discharge pipe. The wastewater discharge pipe extends from the bottom of the secondary cooling chamber body and is provided with a wastewater discharge valve located outside the secondary cooling chamber body.

[0007] Furthermore, a water inlet pipe is connected to the middle of the drain pipe, and the water inlet pipe extends out from the secondary cooling chamber.

[0008] Furthermore, a baffle is provided at the top of the pipe.

[0009] Furthermore, the water supply pipe is a flexible metal hose.

[0010] The beneficial effects of this utility model are as follows: By connecting the water supply pipe and the sewage pipe at the bottom of the drain pipe, impurities in the drain pipe will automatically sink into the sewage pipe under the action of gravity and will not remain in the drain pipe, effectively preventing dirt and impurities from clogging the nozzles in the drain pipe; when cleaning dirt, simply open the sewage valve to discharge the dirt and impurities in the sewage pipe, which is efficient, fast, time-saving and labor-saving.

[0012] In the diagram, 1-secondary cooling chamber body, 2-pipeline, 3-sprayer head, 4-water inlet pipe, 5-baffle, 6-water supply pipe, 7-sewage pipe, 8-sewage valve, 9-sewage outlet. Detailed Implementation

[0013] The present invention will now be described in detail with reference to the accompanying drawings:

[0014] like Figure 1 As shown, a continuous casting secondary cooling chamber drain pipe capable of draining wastewater during online production includes a secondary cooling chamber body 1. An arc-shaped drain pipe 2 is installed inside the secondary cooling chamber body 1. Multiple nozzles 3 are installed along the length of the drain pipe 2. A water inlet pipe 4 is connected to the middle of the drain pipe 2, allowing water to be supplied into the drain pipe 2. The water in the drain pipe 2 can be sprayed out through the nozzles 3, thereby cooling the cast billet inside the secondary cooling chamber body 1. A baffle 5 is installed at the top of the drain pipe 2 to prevent water from spraying out from the top of the drain pipe 2. A water supply pipe 6, which is a flexible metal hose, is connected to the bottom of the drain pipe 2. A drain pipe 7, which is a stainless steel pipe, is connected to the end of the water supply pipe 6 furthest from the drain pipe 2. The drain pipe 7 extends from the bottom of the secondary cooling chamber body 1, and a drain outlet 9 is formed at the outer end of the drain pipe 7. A drain valve 8 is installed on the drain pipe 7, located outside the secondary cooling chamber body 1.

[0015] The method of using this utility model is as follows:

[0016] When it is necessary to spray water to cool the billet in the secondary cooling chamber 1, water can be supplied to the drain pipe 2 through the inlet pipe 4. The water in the drain pipe 2 is sprayed onto the billet through the nozzle 3. At the same time, the water in the drain pipe 2 is also supplied to the drain pipe 7 through the supply pipe 6 and stored in the supply pipe 6 and the drain pipe 7. After a period of use, the sludge or other debris in the drain pipe 2 will sink into the drain pipe 7 under the action of gravity through the supply pipe 6 and settle in the drain pipe 7. At this time, the drain valve 8 can be opened to discharge the oil or other impurities in the drain pipe 7 together with the water stored in the drain pipe 7 from the drain outlet 9 of the drain pipe 7. This is convenient and quick, can quickly clean the dirt in the drain pipe 2 and has a good cleaning effect, greatly saves manpower, and effectively prevents the dirt in the drain pipe 2 from clogging the nozzle 3 and affecting the water spraying effect.
